Why stab three times in a row? Because Yang Yi was manipulating the enemy's arm, making it impossible for him to shoot calmly while forcing him to continuously swing his arm to hit Yang Yi's knife-wielding hand. After drawing the opponent's arm down twice in succession, he stabbed the opponent's eye with the third stab.
Yang Yi was faster, more agile, and he could make the opponent's speed unable to keep up with his reactions, so this was his advantage.
The advantage of being more agile was built on the foundation of the martial skills Yang Yi had learned and practiced, on his experience in dealing with enemies, and even on his physique as an Asian.
But it must be said that Yang Yi has now entered an extremely rare and unprecedented state, at this moment, Yang Yi could be said to have unleashed his full potential. If the same situation happened again, he might be shot dead by the enemy with one shot.
